T=1/p+1/q make q the subject​

Mathematics
1 answer:
Lady bird [3.3K]3 years ago
8 0

Answer:

q = \frac{p}{tp-1}

Step-by-step explanation:

Given

t = \frac{1}{p} + \frac{1}{q}

Multiply through by pq to clear the fractions

tpq = q + p ( subtract q from both sides )

tpq - q = p ← factor out q from each term on the left side

q(tp - 1) = p ← divide both sides by (tp - 1)

q = \frac{p}{tp-1}

Evaluate the integral. (remember to use absolute values where appropriate. Use c for the constant of integration.) 5 cot5(θ) sin
ozzi

I=5\int \frac{cos^{4}\theta }{sin\theta }\times cos\theta d\theta \\\\I=5\int \left ( 1-sin^{2}\theta  \right )^{2}\times \frac{cos\theta }{sin\theta }d\theta \\put\ \sin\theta =t\\\\dt=cos\theta d\theta \\\\I=5\int\frac{t^{4}+1-2t^{2}}{t}dt\ \ \ \ \ \ \ \ \ \ \because (a-b)^2=a^2+b^2-2ab\\\\I=5\left ( \int t^{3}dt + \int \frac{1}{t} -2\int t \right )dt

by using the integration formula

we get,

\\I=5\left ( \frac{t^{4}}{4} +logt -t^{2}\right )\\\\I=\frac{5}{4}t^{4}+5\log t-5t^{2}+c

now put the value of t=\sin\theta in the above equation

we get,

\int 5\cot^5\theta \sin^4\theta d\theta=\frac{5}{4}sin^{4}\theta+5\log \sin\theta - 5sin^{2} \theta+c

hence proved
